How long does it take SIP to actually process a refund

Hi , just wandered if anyone has ever had to wait for a refund from SIP.  In both of my cases I've needed to keep asking for it to happen, the reply seems to be it going on your card, or its going on your card at the end of the month, or, its coming off the value of your next order, and then you still dont see a refund, how long should it take.  When i place an order, i see the transaction on my credit card statement almost straight away, but when you reverse the process its a different story.

I'm waiting for them to refund to my card

 

Its been resolved [;)]
